WILLIAM ISAAC EUKERT, OF SOUTH BETHLEHEM, PENNSYLVANIA BRAKE-BE AM FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed April 16, 1909. Serial No. 490,240.

To all. whom it may concern:

Be it known that I, WiLLLna Isaac Eennn'r, a citizen of the United States, residing at b'outh Bethlehem, county of Northampton, State of Pennsylvania, have invent ed new and useful Improvements in Brake- Beains forRailway-Cars,of which the following is a specification.

Myinvention is an improvement in brake Such beams are shown in U. S. patent of Lamont 782,971, of February 21, 1905, made of two sections ,with bolts securing the sections at top and bottom.

Another form of brake beam is shown in' the patent of (rone 784,839, of Mar. ll, 1905, in which the fulcrum block, as it is some times termed, is made of one piece, lhc bar of which the fulcrum is made being bent backnpon itself. Hy invention belongs to this general type of fulcrum block but is dosigncd to provide a two-piece form with a detachable locking connection at the lower end requiring no bolts.

In the accon'ipanying drawing, Figure l is a general view of my improved device. Fig. 2 is a view with parts detached,'a1nl Fig. 3 shows the parts partially detached.

In the drawing, 1, a portion of the usual bodybeam, and 2, 3, represent the parts of my improved fulcrum which is of the usual construction except as to the connection between the two sections at the lower part. It is desirable to have the parts capable of separation, as in the. patent of lannont, rather than in one piece as in the patent of Crone, but my experience has been that it is also of advantage to dispense with the bolt for connecting the parts together, and I have therefore substituted for the bolt a simple locking connection brought into ell'cctive use when the parts arc brought together. The lower end of each part is providcd with an inward extension (1., which has a downward extension I), 11 mo one cdgc, and a part c cxtcnding inwardly and tcrminafing in an upward extension (I. These parts are rovcr ciy arranged on the sections 2, 3, and it is only necessary in order lo cause the )arts to interlock to bring the lo\.cr ends of t in sections at right angles to each othcr so that the extension I) on the part 2 shall enter the space oz-tween the projccl ion 1/ and the face of the depending part (L of 3. In this position the part 2 is given a quarter turn, bringing the parts in locking engagement, after which a bolt 5 is passed through the usual o 'ienings (3; in the upper parts of the sections, preventing any detachment of the locking connections at the bottom of the sections.

The advantages of my invention, while apparcnt, are cxccedingly important. The parts arc. intcrcliangeablc so that it one should break only that half requires to be replaced, a very important consideration. Further, if the fulerun'i should break a new fulcrum could be. atonce adjusted without rmnlering necessary the taking oli' of the l-nake-shoe or removing the rivets from the brakc-shocs, as necessary with the devices in use at present. Another advantage of thoconstrnction is that not only is there no necessity for a bolt or rivet conniwting the? lower parts together, but no lillcr or washer is necessary in my improved construction.

What I claim is:

1. A fulcrum block for b'rakc boa-ms com posed of two parts, the lower ends of' said parts having interlocking connections, and means for holding the parts in their norma relation, substantially as drscribed.

2. A fulcrum block for bra-kc-lwams composed of two interchangcad le parts, said warts having locking connection at one, end and aholt holding the opposite ends together, substantially as described.

3. A fulcrum block for brake beams composed of two intcrclnmgeable parts, each part having a lower inward extension o, and an interlocking connection, substantially as described.

4. A fulcrum block for brake beams com posed of two parts, eaclrpart having an inward extension (1. at its lower cud, a down' ward: extension 11, a part c and an upward cxtonion d, these parts being rovcrscly arranged and interlocking, substantially as described.

in tcstiinony whcrcof l have signed my name to this specification in lhc prcscncc of two subscribing witnesses.
